Description
The thyroid, or thyroid gland, is an endocrine gland in vertebrates. In humans it is in the neck and consists of two connected lobes. The lower two thirds of the lobes are connected by a thin band of tissue called the thyroid isthmus. The thyroid is located at the front of the neck, below the Adam`s apple. Microscopically, the functional unit of the thyroid gland is the spherical thyroid follicle, lined with follicular cells, and occasional parafollicular cells that surround a lumen containing colloid.
